Does anyone know anything about them? (Not even sure if this is the right place to post this.)
I heard about these a while ago, but beta is tough to find.
I found this indicating they are back filling them, http://www.ecprogress.com/index.php?...rticle_id=7659, but that the "powder magazine" in buckhorn draw will be left open for "historical value".
Anyone know where that is, or even much else about these?
